Answer:

(i) ∠CDF = 86°

(ii) ∠BAD = 141°

Step-by-step explanation:

(i) Angles CDF and GFD are "alternate interior" angles, so are congruent.

∠CDF = 86°

(ii) Angles BAD and CDA are "alternate interior angles, so are congruent. Angle CDA is the sum of angles CDH and HDA. Angle CDH is supplementary to angle CDF, so is ...

∠CDH = 180° -∠CDF = 180° -86° = 94°

Then ...

∠CDA = ∠CDH +∠HDA = 94° +47°

∠CDA = 141°

A ray of light with intensity lo falls vertically on the sur face of the sea and at ten meters deep its intensity is 10/3. Assum

seropon [69]

Answer:

intensity = $\frac{Io}{15}$

intensity = $\frac{Io}{30}$

depth = 333.33 m

Step-by-step explanation:

given data

deep = 10 m

intensity = Io

intensity = Io/3

to find out

intensity of light at 50 m and 100 m and 1/100 of initial intensity remain ?

solution

we know here that intensity is inversely proportional to deep so

intensity = k × $\frac{1}{Deep}$ .................1

here k is constant

so we have given 10 m deep so

$\frac{Io}{3}$ = $\frac{k}{10}$

so k = Io × $\frac{10}{3}$ ................2

so from equation 1 when 100 m deep and 50 m deep

intensity = k × $\frac{1}{Deep}$

intensity = Io × $\frac{10}{3}$ × $\frac{1}{50}$

intensity = $\frac{Io}{15}$

and

intensity = Io × $\frac{10}{3}$ × $\frac{1}{100}$

intensity = $\frac{Io}{30}$

and

at intensity Io/100

intensity = k × $\frac{1}{Deep}$

$\frac{Io}{100}$ = Io × $\frac{10}{3}$ × $\frac{1}{D}$

D = 333.33 m

so depth = 333.33 m

If 2/7=6 then 1/7=3
So 3×7=21 I think

Answer: a) 8%

b) 34%

c) 12%

<u>Step-by-step explanation:</u>

$a)\quad \dfrac{January\ Clothing}{January\ Payments}=\dfrac{234.75}{2800.00}=0.083\implies \large\boxed{8\%}\\\\\\b)\quad \dfrac{January\ Housing}{January\ Payments}=\dfrac{945.20}{2800.00}=0.337\implies \large\boxed{34\%}\\\\\\c)\quad \dfrac{January\ Transportation}{January\ Payments}=\dfrac{347.46}{2800.00}=0.124\implies \large\boxed{12\%}$

I need to know which ones are parallel and which ones are perpendicular and the steps thank youu

defon

Answer:

If both equations have the same slope, they are said to be parallel.

If an equation is the reciprocal of another equation (meaning flipped denominator and numerator as well as flipped +/- sign) they are said to be Perpendicular.

Hope it helps!
